Claims (1)

[Claims for Utility Model Registration] In a mechanism for attaching the projector body 1, which is to project an image onto the screen 12, to a wall surface corresponding to the screen 12 in such a manner that the inclination angle can be adjusted, It is composed of a first support mechanism that pivots the lower part of the projector body 1, and a second support mechanism that supports the upper part of the projector main body 1 so that it can approach and move away from the wall surface. 51 and is attached to the wall side in a direction protruding from the wall surface, and a claw 31 that can engage with the tooth surface 51 of the rack member 5 and is attached to the projector main body 1 side.
1, a rotary knob 2 rotatably arranged on the outer surface of the projector body 1, and the slide plate 3 reciprocated in conjunction with the operation of the rotary knob 2. A wall-mounted tilt angle adjustment mechanism for a projector, characterized in that it is equipped with a cam mechanism that allows the projector to be mounted on a wall. In a mechanism for attaching the projector main body 1, which is to project an image onto the screen 12, to a wall surface corresponding to the screen 12 so that the inclination angle can be adjusted, a first and a second support mechanism that supports the upper part of the projector main body 1 so that it can approach and move away from the wall surface, and the second support mechanism includes a rack-shaped tooth surface 83 that protrudes from the wall surface toward the wall surface. The rack member 8 is provided with a claw 94 that can engage with the tooth surface 83 of the rack member 8, and is pivotally supported on the logicector main body 1 side so as to be able to approach and separate from the tooth surface 83 of the rack member 5. A rotating plate 92, a spring 95 that biases the rotating plate 92 toward the rack member 5, a push button 7 arranged on the outer surface of the projector main body 1 so as to be pressable, and a push button 7 that can be operated by pressing the button 7. A wall-mounted inclination angle adjustment mechanism for a projector, characterized in that it is equipped with a shaft piece 75 that moves in conjunction with each other to press a rotating plate 92 against spring bias.
